Avalanche, landslide, or mudslide, subsequent encounter

This code indicates that a patient is being treated for injuries or conditions sustained from an avalanche, landslide, or mudslide, and this is not their initial presentation for these issues. It signifies ongoing care, follow-up appointments, or treatment for complications arising from the original event.

Apply this code for patients returning for physical therapy after a mudslide-related fracture, follow-up appointments for psychological trauma from an avalanche, or management of chronic pain stemming from injuries sustained in a landslide. It is appropriate for any encounter subsequent to the initial treatment for the natural disaster event.

• Ensure documentation clearly states this is not the first encounter for the specified injuries.
• Always sequence this code after the primary diagnosis describing the specific injury or condition being treated.
• Verify the encounter type is indeed subsequent and not an initial presentation or sequela (which has a different seventh character).
